INHALER WITH BOUNDARY ELEMENT Russian patent published in 2022 - IPC A61M15/00 A24F42/20 A24F42/60 

FIELD: tobacco industry.

SUBSTANCE: group of inventions relates to an inhaler product and an inhalation system. The inhaler product contains a case passing along the longitudinal axis from the mouthpiece end to the far end. The product includes a capsule cavity formed inside the case and passing along the longitudinal axis. The product contains a mouthpiece air channel passing from the capsule cavity to the mouthpiece end. The product contains a boundary element located between the capsule cavity and the mouthpiece air channel and containing at least two concentric rings of holes connecting the capsule cavity to the mouthpiece air channel via fluid, a central area, which corresponds to the longitudinal axis, and a perimeter area, which contacts the case, wherein the central area is a solid circular area coplanar with a perimeter. The product contains an outer concentric ring of holes, which surrounds the inner concentric ring of holes, and each of inner holes of the inner concentric ring of holes has a cross-sectional area smaller than that of each of outer holes of the outer concentric ring of holes.

EFFECT: improvement of the possibility of delivery of particles due to the improvement of the dynamics of an air flow or fluid and maintenance of the stability of the rotation of a capsule.
